BACKGROUND ART

Parcel sorting includes dispensing packages going to differentdestinations to different exits through a delivery device, so as torealize unified transport of packages going to the same destination.This is especially advantageous in a order fulfillment center orshipping facility. Generally, a parcel containing articles for shipmentwill have a UPC, barcode, SKU, or similar that allows for identificationof the parcel identity and destination.

Article sorting includes dispensing articles that come from a pluralityof warehouse locations to different exits through a delivery device, soas to realize unified consolidation at a single exit or destinationpoint of all articles in a single order going to a destination in asingle package or parcel. This is especially advantageous in any type ofparcel fulfillment center.

The process is very labor intensive, which increases cost, errors inprocessing, and increases the time for packages to arrive, all lesseningthe end customer experience. Additionally, packages may be damaged,mispackaged, and the like, reducing efficiency for all involved parties.
